People with acne had an 18.5 per cent chance of developing depression compared with 12 per cent of those without over the 15 years.

The researchers also found that the risk for major depression was highest within one year of acne diagnosis – a 63 per cent higher risk compared with individuals without acne – and decreased thereafter.

"This study highlights an important link between skin disease and mental illness," said lead author Dr. Isabelle Vallerand, of the University of Calgary.

“Given the risk of depression was highest in the period right after the first time a patient presented to a physician for acne concerns, it shows just how impactful our skin can be towards our overall mental health."

"For these patients with acne, it is more than a skin blemish - it can impose significant mental health concerns and should be taken seriously."

The Australian organisation All About Acne stresses on its website that “Studies show acne can be linked to social isolation, self-consciousness, low self-esteem, reduced employment prospects, anxiety, depression and even suicidal thoughts so it's important to seek medical help as soon as possible.”

This study encourages healthcare professionals to take patients’ skin concerns seriously and find ways to help them treat both the physical and mental impacts of the skin disorder.
